The Memory Bandwidth chart for a displays the estimated DRAM Read bandwidth graph and estimated PMem Read Bandwith graphs for a virtual machine.

This chart is available in the Memory pane of the View dropdown menu of vSphere Client for a virtual machine at Performance > Overview tab. The Memory pane gives information about Memory Bandwidth in addition to the Memory Usage and Memory Reclamation information.
Note: If the host supports vMMR and is in memory mode, Memory option is listed in the View dropdown menu. In other cases, Memory option is not listed.
